Electronic Properties Close to Dirac Cone in Two-Dimensional Organic Conductor -(BEDT-TTF)I
Shinya Katayama, Akito Kobayashi, Yoshikazu Suzumura
A zero-gap state (ZGS) has been found in a bulk system of two-dimensional organic conductor, -(BEDT-TTF)I salt which consists of four sites of donor molecules in a unit…
Role of Interlayer Electron Hopping for Spin Density Wave State in the Zero-Gap Organic Conductor
Shinya Katayama, Akito Kobayashi, Yoshikazu Suzumura
We investigate the formation of density waves in the zero-gap state (ZGS) which has been found in the quasi-two-dimensional organic conductor -(BEDT-TTF)I salt under the…
Electric Conductivity of the Zero-gap Semiconducting State in Alpha-(BEDT-TTF)2I3 Salt
Shinya Katayama, Akito Kobayashi, Yoshikazu Suzumura
The electric conductivity which reveals the zero gap semiconducting (ZGS) state has been investigated as the function of temperature and life time in order to understand th…
Pressure-Induced Zero-Gap Semiconducting State in Organic Conductor -(BEDT-TTF)I Salt
Shinya Katayama, Akito Kobayashi, Yoshikazu Suzumura
We show a zero-gap semiconducting (ZGS) state in the quasi-two-dimensional organic conductor -(BEDT-TTF)I salt, which emerges under uniaxial pressure along the a-axis (t…
On the Magnetic Excitation Spectra of High Tc Cu Oxides up to the Energies far above the Resonance Energy
Satoshi Iikubo, Masafumi Ito, Akito Kobayashi +2
Magnetic excitation spectra c"(q,w) of YBa2Cu3Oy and La214 systems have been studied. For La1.88Sr0.12CuO4, c"(q,w) have been measured up to ~30 meV and existing data have been ana…
Studies on Magnetic Excitation Spectra of High-Tc Superconductors
Masafumi Ito, Yukio Yasui, Satoshi Iikubo +6
Magnetic excitation spectra c"(q,w) of YBa2Cu3Oy, La2-xSrxCuO4, La2-y-xNdySrxCuO4 and Nd2-xCexCuO4 are compared with those of model calculations, where q and w are the wave vector…
